3.10.1. Maneuver Description . Entry to the Four-Point roll can either be initiated using a Split ìSî
or Sliceback maneuver from the perch point achieved from the Show entry maneuver. A pull up of 5.0
to 6.0 Gs is initiated from either maneuver at 1,200 feet AGL to arrive on the 1,500-foot show line at
500 feet AGL and 350 knots. 2,000 feet prior to show center, pull the nose 3 to 5 degrees nose high,
establish a climb, and unload. A cadence four-point roll to the left is then performed by pausing
momentarily at the 90-degree, 180-degree, 270-degree, and 360-degree points. The pace of the
cadence should ensure the aircraft is at the 180-degree point over show center. In order to facilitate
sharp transitions between each 90 degrees of roll, momentarily ìfanî the speed brakes and unload the
aircraft to 0 Gs at the initiation of each roll. Be sure to close the speed brakes upon completion of the
roll to avoid any unnecessary loss of airspeed. The 90-degree and 270-degree points require top rudder
to maintain level flight and zero G to maintain the show line. The 180-degree point requires 1 negative
G in order to maintain level flight. This is accomplished using the horizon, not the G meter. At
the completion of the Four-Point Roll, begin the Cuban 8 (high show) or 360-degree level turn (low
show).
3.10.2. Abnormal Procedures: If at anytime during the Four-Point Roll, the nose falls more than
five degrees below the horizon, abort by rolling towards the nearest horizon and a wings-level position,
then continue down the show line. This would most likely occur during the 3 rd point (270
degrees) due to a decrease in airspeed, which results in less rudder effectiveness.
